With the continuous development of the semiconductor industry, the scale of digital integrated circuits is getting bigger and bigger, and the degree of integration is getting higher and higher. In modern applications, speed has become an indicator that people pay much attention to. In a digital system, the overall performance is greatly affected by the calculation speed of the multiplier, because the arithmetic logic unit (ALU) is one of the most time-consuming parts of the digital system. In this dissertation, a 16-bit high-speed multiplier was designed using Verilog hardware description language and compared with several commonly used multipliers. First, this dissertation introduces the basic process of digital circuit design and the b...
